CAB39 and urinary bladder carcinoma: They indicated that compared to normal bladder cancer cell lines, cisplatin-resistant muscle-invasive bladder cancer cells show increased expression of calcium binding protein 39 (CAB39), causing activation of liver kinase B1 (LKB1), adenosine monophosphate-activated protein inase (AMPK), and microtubule-associated protein one light chain 3 (LC3), which makes the cells more likely to survive (Gao et al., 2023).
